Donald Clayton and Wolfgang Hillebrandt with Dagmar
Hillebrandt in Munich Biergarten. (See Darmstadt Renaissance in 1977
photo for the first meeting of these two.) Thielemann, who snapped this
shot, accompanied Hillebrandt from Darmstadt. They now count among the
primary leaders of nuclear astrophysics in Europe. This photo is on
Aug. 11, 1981; see next entry for another including Thielemann on the
same occasion. This followed Clayton's lecture "Extinct
Radioactivities: a three-phase mixing model (ApJ 268, 381 (1983))" at
MPI on this date.
